Wireless charging

Nuvoton proposes three solutions that are compatible with the Qi standard: 5W, 7.5W/5W, and 15W/5W, as well as a 5W solution that is compliant with the Qi standard. The conversion efficiency can reach 85%, the power can be adjusted dynamically, and both have protection functions such as over-temperature, current limiting, and metal foreign object detection. The 5W solution that complies with Qi standards has passed Qi Ver 1.1.2 certification (No.: GZES1411013461IT).

Program features:

• 5W single coil, FM
• Compatible with Qi Ver1.2.4 standard, A11
• Dynamic power adjustment, efficiency 72%
• Metal Foreign Object Detection (FOD)
• With over-temperature, current limiting and other protection functions
• Charging/power off/dynamic power status indication
